安徽省森林生态网络指标体系及其评价方法的探讨

选用当前国内外常用的评价可持续发展的模型 ,即压力—状态—响应模型 ,分析安徽省森林生态网络建设的重要相关因子现状 ,找出干扰和影响安徽省森林生态的稳定与发展的因素 ,初步构建了安徽省森林生态网络指标体系。采用层次分析法结合专家意见咨询法 (德尔菲法 )计算出约束层与指标层对目标层的权重 ,调查 6个不同类型区县各指标现状值 ,分析评价其森林生态网络综合指数并进行了排序 ,并据此评价建设单位不同时段森林生态网络建设的效果及其与标准 (目标 )值的差距 ,结果比较符合实际

The Study of Indicator System and Evaluation Methods for Forest Ecological Network in Anhui Province

The popular model for sustainable development evaluation used abroad and domestically, i.e. the model of Driving force-State-Response was Introduced in this paper. The concerned important factors of construction of Forest Ecological Network in Anhui was analyzed and the kind of driving forces which affect the stability and development of forest ecological environment in Anhui were found out, the indicator system for the network was initially formed. The paper calculated the heavy balance of constraints and indicators to the targets by the Analytic Hierarchy Process(AHP) and experts' consultancy way (Delphi Way), outlined the present value of the indicators in 6 different typical counties, and analyzed their forest ecological comprehensive indicators and put them in order, from which the paper evaluated the effects of forest ecological network construction in different stages and the differences to the final target. The results of the study fit the fact.
